Copyright, use and redistribution information. 10 README ........ This file. 11 build ......... Build directory. 12 catalog ....... Message catalogs; see catalog/README. 13 cl ............ Vi interface to the curses(3) library. 14 common ........ Code shared by ex and vi. 15 docs .......... Ex/vi documentation, both current and historic. 16 ex ............ Ex source code. 17 regex ......... Modified regex library with wide character support. 18 vi ............ Vi source code. 19 20=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 21 22o Nvi was written by Keith Bostic, and the last version is 1.79. After that, 23 24 Sven Verdoolaege added the iconv support and the DB3 locking. 25 26 Jun-ichiro itojun Hagino developed the file encoding detection 27 techniques in his nvi-m17n. 28 29The following acknowledgments were written by Keith Bostic: 30 31=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 32o This software is several years old and is the product of many folks' work. 33 34 This software was originally derived from software contributed to 35 the University of California, Berkeley by Steve Kirkendall, the 36 author of the vi clone elvis. Without his work, this work would 37 have been far more difficult. 38 39 IEEE POSIX 1003.2 style regular expression support is courtesy of 40 Henry Spencer, for which I am *very* grateful. 41 42 Elan Amir did the original 4BSD curses work that made it possible 43 to support a full-screen editor using curses. 44 45 George Neville-Neil added the Tcl interpreter, and the initial 46 interpreter design was his. 47 48 Sven Verdoolaege added the Perl interpreter. 49 50 Rob Mayoff provided the original Cscope support. 51 52o Many, many people suggested enhancements, and provided bug reports and 53 testing, far too many to individually thank. 54 55o From the original vi acknowledgements, by William Joy and Mark Horton: 56 57 Bruce Englar encouraged the early development of this display 58 editor. Peter Kessler helped bring sanity to version 2's 59 command layout. Bill Joy wrote versions 1 and 2.0 through 2.7, 60 and created the framework that users see in the present editor. 61 Mark Horton added macros and other features and made the editor 62 work on a large number of terminals and Unix systems. 63 64o And... 65 The financial support of UUNET Communications Services is gratefully 66 acknowledged. 67
